I have an ART SLA-1 Rack amp up for sale, its in good condition, some scratches on the top and bottom of it from racking. It is only about a year and a half old, I am the original owner. It does NOT come with the original manual and box though. It is rated at 100wrms per channel @8ohms and 130wrms at 4ohms, 260wrms bridged at 8ohms.

This is a great amp for powering a pair of bookshelves, or an addition to going active for a set of mids/tweeters.
